Treasure Data interview questions

First call with a recruiter. After that, a one hour interview with the hiring manager. I have not had the chance to continue further as the recruiter ghosted me despite reaching out to him a few times. I also want to add that the same recruiter initially cancelled the first interview only few minutes before the start of the call saying that for this specific role industry knowledge was mandatory. This was not outlined in the job description. I challenged that, and he rescheduled the interview which led to a second round with the hiring manager. After that I have not heard anything. Poor experience and very disappointing.
